Paparazzo Paul Raef was eventually charged under California's new paparazzi laws, which impose harsher penalties for paparazzi who drive recklessly or create a sense of "false imprisonment" in their pursuit of photographs of celebrities.

Raef's lawyer David Kestenbaum has now told E! News that he has asked for Raef's arraignment to continue so that he can challenge the new laws.

"It's going to be an interesting First Amendment issue," he said. "We are probably going to have a legal challenge to the new law... It targets a special group of people, which is another constitutional issue."

The anti-paparazzi laws would mean that, if convicted, Raef's penalty could rise from 90 days in jail and a $1,000 fine to six months in jail and a $2,500 fine.

Kestenbaum, who vowed to speak to all of the witnesses to the incident including Bieber, claimed that there is "no need to enhance penalties just when celebrities are being chased".
